Diamonds aren’t that dense, they’re just hard… In fact, the cubic structure makes them less dense than graphite, I think. Diamond-based pencils would ruin a lot of paper, though, unless you used a lot of wax… Hey, that’d be cool.

You couldn’t kick anybody. The Saturn Gravity boots cause your feet to be immovable from the ground, and if you kicked with the anti gravity boots on, you would just go into a constantly repeating flip until you turned them off.

The gravity relative to the Earth of Saturn is .916, so the saturn-gravity boots would actually make him weigh less, but not as much less as the anti-gravity boots would, but DMC_Run was right, density is relevant to gravity (and it’s low density is only because the atmosphere is 97% Hydrogen and 3% Helium, and so much of Saturn is atmosphere that even the extraordinarily dense core only brings the average density to .678g/cc), Saturn is about 95 earth masses, and with the large radius, the d^2 murders G. The anti-gravity boots wouldn’t be negative gravity (as shown in pic) but would most likely put Biff in a state of micro-gravity, or approximately 0Gs; similar to Joanassie’s point.
